Abstract (en)
[origin: WO2022107808A1] In this light control sheet, a first transparent electrode layer (41A) includes a driving electrode element (30) that is a first electrode element, and a floating electrode element (31) that is a second electrode element. The driving electrode element (30) and the floating electrode element (31) are separate layered bodies arranged along a support surface (46S) of a first transparent support layer (42A), and are electrically isolated from each other by a groove (32) extending in a direction along the support surface (46S). The groove (32) penetrates the first transparent support layer (42A) and the first transparent electrode layer (41A) in a depth direction, and has an opening (33) in a surface to be protected (46P) of the first transparent support layer (42A). The opening (33) is covered with a covering layer (45).
